Specification of Letters Patent.

Application filed March S, 1912. Serial No. 682,545.

To @ZZ Iwhom it may concern lie it known that l, VLADIMIR V. MESSER, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles, tate of California, have invented a new and useful Concrete-Pipe-Making Machine, of which the following is a specification.

rlhis invention relates to pipe-making Inachines, and the main object of the invention is to provide a machine which will produce pipe sections with great rapidity.

@ther objects and advantages will be brought out in the following description.

Referring to the drawings, Figure 1 is a vertical longitudinal section through the machine. Fig. 2 is an enlarged cross section on line .fc3-:02, Fig. 1. Fig. 3 is a section on line .fc3-m3, Fig, 2. Fig. 4 is a section on line ait-m4, Fig. 3. Fig. 5 is a section on line a5-05, Fig. 3. Fig. 6 is a section on line ref-, Fig. 2. Fig. 7 is a section on line .mL-m7, Fig. 2. Fig. 8 is plan view of the machine. Fig. 9 is a section on line .t9-509, Fig. 8. Fig. 10 is a side elevation in detail of the mo-ld. Fig. 11 is a section on line .tu-, Fig. 10. Fig. 12 is an enlarged section of the device for detachably securing the cone to the core. Fig. 13 is a. perspective of the clamp. Fig. 14 is a perspective of the ring and tamping blades. Fig. 15 is a side elevation of the detachable screw thread connection.

The` frame of the machine consists of a lower plate l, an upper plate 2, and an intermediate plate 3, which are supported by vertical rods 4. A main shaft 5 extends along the center of the machine, its lower end being journaled in a bearing 6 and its intermediate portion in a sleeve 7, the sleeve 7 being mounted in abearing 8 on the frameplate 3. A thrust-bearing 9 is provided at the lower end of the sleeve 7 and a` thrustbearing 10 is provided at the upper end of the sleeve 7.

Supported above the thrust-bearing 10 is a disk 11, having radial T-slots 12, with upwardly projecting teeth 13. Supported on the disk 11 is a table 14, having lugs 15 which support a shouldered ring 16. The ring 16 furnishes a core-support, and there may be various sizes of rings 16 provided with the machine in order to accommodate different diameters of cores, and for this reason the T-slots 12 and teeth 13 are rovided, which enable diiferent sized tables 14 and rings 16 to be employed. Bolts 17 secure the table 14 to the T-slots 12. Thus if a larger table 14 is to be used, the T-slots 12 and teeth 13 accommodate the larger size of the table. The teeth 13 hold the table positively in a central position with respect to the main shaft 5, while the T-slots 12 permit the bolts 17 to be adjusted radially.

Supported on the ring 16 is a cylindrical core 18, which extends up through a plate 19, which is secured to a split ring 20 shown in 'detail in Fig. 13. The plate 19 has shouldered lugs 21 which engage a ring 22 on the lower end of a cylindrical mold 23. Un the upper end of the core 18 is a ring 24 with tamping blades 25 arranged at an angle as shown in detail in Fig. 14, and above the ring 24 is a cone 26 with handles 27 anda guide 28. Slidable over the guide 28 is a cap 29, which is secured to a stem 30, the latter being slidable through the guide 28 and at its lower end having a slotted cross head 31 with rollers 32 which are adapted to engage a pair of arms 33` which are pivoted at 34 to a ring 35 secured by bolts 36 against the underside of an inwardly projecting flange 37 on the ring 24, the bolts 36 being screwed into inside lugs 38 on the cone 26. The lower ends of the arms 33 are held by springs 39 in engagement with screw threads 40 on a short shaft 41, which is in line with the main shaft 5 and secured thereto by a coupling 42. The threads 40 have abrupt shoulders, as clearly shown in Fig. 15, which enable the arms to be quickly shoved down over the threads to engage therewith while the shaft is rotating. By pressing down on rod 30 the cross head 31 will tilt the arms 33 and release them from the threads. The purpose of this construction is to permit quick attachment or detachment without stopping rotation of the shaft. Immediately after attachment, the rotation of the shaft causes the threads to screw down on the shaft and take up all slack. The shaft 41 extends through a hub 43, from which arms 44 extend to the core 18 so that the core 18 is held centrally on the shaft. Rotation of the core is effected through the table 14 and lugs 15.

The shaft 5, sleeve 7, and parts supported thereby, with the core 18, are capable of vertical movement to carry the core 18 up into the mold 23 as the operation of making a length of pipe progresses. The shaft 5 and parts rotated thereby are kept under constant rotation by means of a gear 45 on Eatented Oct. 6, 1914.

the shaft 5 which meshes with a long pinion il-G which permits the gear l5 to rise with the shaft 5 and still maintain its mesh with pinion 16.

is shown in l", secured to one side of the sleeve 7 is a racl; li' which meshes with a pinion i8 which is mounted on a shatt lll in bearings 50 and having a sprocket 5l which is connected by chain with. a sprocket 53 which is operated by a clutch consisting ot two members 5l and 55, both of which are n'iounted on shaft 5G, the sha/lit 5b being iournaled .in bearings 5i' and having a gear '5l-5 meshing with a gear 59 on the driving shaflft (il), which journaled in bearings (Si and G2 and drii.v yri by a pulley 62 through the medium oll a clutch 64;.

@n the shailt atl) is a ratchet wheel (l5 which, as clearly shown in Fig1 t3, is engaged by a pawl GG pi'voted at (ST, and also by an pperating. pawl G'rlpiroted G9 to an arm d() which is pivot lly su pported on 'the shalt 49, the pawl also being connected by a link 7l with the lower' end or" a lever which is pivoted at T8. in eccentric rod ill is connected at 'T5 to the arm "i0 and op Vrated bj an eccentric T6 on shaft 5G. A rod 7T is pivotally connected to a cranlrarm T8 carried on a shaft T9 mounted in a bracket SO projecting trom bearing Gl, as shown in Fig. rhe rod 77 has three collars 8l, 82 and 83 rigidly secured thereto and has sliding collars S-l and 85. rllhe collar Sil has a: pin 8G which engages the re taining pawl 6G, while the collar 85 has af pin 8T which loosely engages the arm 72.

A coil spring` 88 is arranged between the rigid collar 82 and the sliding collar S-land thus serves to normally press the pivotal point 86 to the right and hold the pawl (56 yieldingly in enga gen'ient with the ratchet ('35, thereby preventing the ratchet (35 from moving rearwardly. A coil iring S9 bears against the rigid collar 83 and ag sliding collar 85 and holds the arm ingly toward the ratchet wheel G5.

lis the arm 70 is rocked by the eccentric 76 it actuates the pawl GS so that the latter moves ratchet wheel one tooth at a time,

the pawl 68 being yieldingly held against the ratchet wheel by the spi T2. pressure ot both springs 88 and S9 is reng-pressed arm moved against their respective collars Se! and 85, and the rigid collars el and S2 respectively bear against the sliding collars 84 and and positivelyT swing the retaining pawls 66 and arms 72 and upper end ot pawl ('58 to the lett, thereby disengaging both pawls (56 and (i8 `from the ratchet wheel 65, this engagement being accomplished even though the arm 70 is continuously rocked by the eccentric. By moving the rod 77 to the right again the pawls are caused to rengage the ratchetl G5 and are kept in such engageost the By n'ioving the rod 77 to the lett, the

ment by the pressure of springs S8 and S9. also mounted on the shaft 56 is a clutch consisting et members 90 and 9i., the member 9i being connected with the eccentric 76 so that when both members 90 and 91 are in engagenient the eccentric is operated, while when the members 90 and 91 are disengaged the eccentric is not operated.

ris shown in liig. 8, a sleeve 92 slidable on shatt 5G is connected to the clutch member 55 and a sleeve 92 also slidable on sha'tt 5G is connected to clutch member 90 and to sleeve 92 and forms virtually a continuation et sleeve 92 so that when the sleeve 92 is operated both clutch membe 's are operated. Both sleeves are attached to a slotted member 93, which is actuated by an arm 94.- on shaft 95. rllhus when the sleeve 92 is moved to the right, the clutch member 90 is engaged with clutch member 91, and clutch member 55 is moved away from and disengages the clutch member 5l, while by moving the sleeve 92 to the left clutch member 55 may be engaged with clutch member 3f-l, and clutch member 90 disengaged from clutch member 91, or by moving the sleeve 92 to central position both clutch members and 9() will be held out of engagement with clutch members 54 and 91.

in order to prevent shock to the machine, the clutch members 55 and 90 are each formed et a hub c with wings Z) and a box c, with inwardly projecting wings al, as shown in Figs. il and Between the wings Z) and al are rubber segments e. The hubs o are secured to the sleeves 92 and 92, while the boxes o are loose in the sleeves and provided with lugs f for coacting with the associated clutch members. The interposed rubber segments cushion the clutching action.

An arm 96 is secured to one end of the shaft and projects into the channel in the side of the raclr il?. Secured to the rack t? is a stop 97 and a stop 98 as shown in Fig. 7, the stop 98 being adapted to strike the arm 96 at the limit of upward motion et rack il? and thereby automatically stop iun ther upward movement of the rack il?, by rocking shaft 95 in the direction ot the arrow, Figs. 2 and 7, and through arm 93 move both clutch members 90 and to central position, thereby disengaging both clutches and stopping the operation oit the eccentric 76, thus stopping actuation oi'. pawl (38 and actuation of ratchet This turning movement of shaft 95 operates through segmental bevel gears a" and y/ to turn shaft 79 in the direction et the arrow, Fig. 6, and push rod 77 to the lett thereby disengaging the pawls GG and 68. The downward travel of the rack and core is caused to commence by operating hand lever clutch 'member` 511, thereby causing shaft 56 l When the shaft 106 is turned in either dito be rotated in the direction of the arrow, 2, and through the nedium of the sprocket and chain connection drive. shaft #19 in a direction opposite to the arrow, Fig. 2, thereby moving the rack 47 and core downwardly. This same movement of shaft acts through segment gears fc and g/ to turn shaft T 9 still farther and this keeps the ratchet mechanism inoperative so that the downward movement is accomplished by the sprocket and chain connection and is a continuous steady movement. At the limit of downward movement the stop 97 strikes the arm 96 and rocks the shaft 95 in the direction opposite the arrow, Figs. 2 and 7, thereby through the medium of arm 9a moving both clutch members 55 and 90 to midposition thereby releasing clutch member 5a which stops the operation of shaft and further downward movement of rack L17. tt this time, although shaft 60 continues to revolve shaft L19 remains stationary because both clutches are in mid position and neither the sprocket and chain connection or ratchet mechanism are operating. TWhen the upward travel is to be produced, the lever 110 is operated to pull up on link 115 and turn shaft 95 in a direction opposite to the arrow, Fig. 2, thereupon moving clutch member 90 from mid position into engagement with clutch member 91 causing the eccentric 76 to operate the pawl 68 of the ratchet mechanism. This same turning movement of the shaft 95 operates through the bevel segment gears c@ and y to turn shaft 7 9 in a direction opposite the arrow, Figs. 2 and 6, and pull rod 4T7 in the direction opposite the arrow, Fig. 6, thereby bringing pawl 68 into operative engagement with ratchet and as the eccentric 76 is now operating and the pawls 68 and 66 are in engagement, the ratchet mechanism becomes operative and imparts intermittent rotation to shaft 19 and the latter imparts an intermittent upward movement to rack 117 and the core, which continues until the upward limit of movement has been reached where further upward movement is automatically stopped.

The pinion e6 has a bevel gear 99 on its upper enc., see Figs. 1 and 2, which meshes with a bevel gear 100 on shaft 60 by means of which the pinion 116 is rotated.

The split ring members 20 are expanded or contracted, as shown in Fig. 13, by means of a pair of upper rods 101 and lower rods 102, which pass through both ring members, as shown, the upper rods 101 being secured by pins 108 to the right hand member 20 in Fig. 13, and the lower rods 102 being secured by pins 104; to the left hand member 20. The rods are provided with racks 105 and a shaft 106 is provided with gear teeth 107 which mesh with the racks 105 and is provided with a handle 108 for operating it.

rection it operates the rods 101 and 102 in opposite directions. Thus, looking` at 1B, when the lever 108 is swung to the left, rods 101 will move to the left and rods 102. move to the right, thereby moving both collar members 20 closely together, while when the lever 108 is moved in the opposite direction the collar members 20 will be moved apart.

Loosely mounted on the shaft 106 are bell crank levers 109 and 110. The lever 109 is connected by a link 111 with an arm 112 on a shaft 118, see igs. 1 vand2, and forked levers 11d carried by a shaft 113 operate the clutch 651. rlhe lever 110 is connected by a link 115 with an arm 116 on shaft 95 for operating the latter shaft. rl`hus by operating the lever 109 the entire machine may be started or stopped, and by operating` lever 110 the clutch members' or 90 may be placed in mid position, or either engaged with its cooperating clutch member.

The mold 23 is shown in detail in Figs. 10 and 11 and is of well `known construction, being` a cylindrical sheet metal member, split longitudinally at 117, and eye-bolts 118 are pivoted to brackets 119 riveted at one side of the opening 117, the eye-bolts being connected to shackles 120 which are connected to a rod 121 having arms 122 which are pivoted to brackets 123. A handle 124: is secured to rod 121 so that by swinging the handle 12A outwardly the mold 23 will be expanded, while by swinging the handle 1241- inwardly the mold 28 will be contracted into the position shown in Fig. 11.

1n operation the parts stand as shown in Fig. 1 at the commencement of making` a pipe section. The shaft 5 is under rotation and the core 18 is being rotated. Concrete is introduced into the mold from the spout ai, Fig. 12, the concrete falling to the bottom of the mold and resting on the blade 125. is the machine operates, the core is moved upwardly by the before described ratchet mechanism, the core rotating as it rises and the spiral blades 25 screw the concrete downwardly and act as tampers to pack the concrete solidly in the annular space be tween the core and mold. l/Vhe'n the core arrives at the top, its further upward movement is arrested by the before described stop mechanism. rllhen by pushing` down on rod 30, the arms are freed from threads 410, and by grasping handles 37, cone 32 may be lifted olf and then the ring 2st which carries spiral blades 25 may be removed. Then lever 110 is operated to place clutch member 55 in engagement with clutch member 54:, w iereupon the downward travel of the core commences. while still rotating. The downward travel of the core is stopped at the end of its movement by automatic mechanism before described. Lever 108 is operated to epeii the clamp member 20 and then the mold with the nieided pipe iaeetien Within it iiit'ted from the plete 19 and :met-her meid is phi/eed iii the iimehiiie, ready ei the Operation of milking the next pipe eeetieii.
